In their own words
Serpvox
Serpvox is a web-based keyword research tool for SEO specialists. A search combines Google Trends interest, estimated keyword difficulty and intent, and the top 10 Google results. Its difficulty calculation uses the average PageRank of those results, adjusted for featured snippets and the knowledge graph. Trends cover the previous 12 months and refresh on each search; the tool also shows People Also Ask questions and Related Searches from Google’s results. Users can connect Google Search Console to view a site’s organic traffic. Serpvox says that connection is read-only and can be disconnected at any time. Its stated data sources include Google Autocomplete, Google Trends, SERP analysis, OpenPageRank, and connected-site Search Console data. Pro supports CSV, Excel, and PDF exports; Agency adds multi-site Search Console, batch export, and priority support. Free is free, billed forever, with a limit of 3 searches per day and 30 per month. Pro costs €19 a month, Agency €49 a month, and a 7-Day Pass costs €9, paid once.
